Bags and backpacks
If you have a choice in the bag or backpack for your school, look for a durable one that will last many years. Backpacks need to be tough as they often have to carry heavy loads and get quite a beating.
You can look for packs made from recycled material or natural material such as hemp. You can even get solar powered backpacks which can be used to charge technology like portable music players, cameras and radios. Try to avoid backpacks made from resource-intensive vinyl (PVC), plastics or nylon.
Look for a pack with compartments to help distribute the weight. Pack the heaviest things in first; the closer they are to your child's back, the less strain they'll put on young muscles.
